Title: Improvements in the production of cyclohexanone
Inventor: POEHLER GUENTER
IPC: C07C45/00
Filed: 1958-11-14
Abstract: In a process for the production of cyclohexanone by dehydrogenation of cyclohexanol which has been obtained by reacting aniline or nitrobenzene with steam and hydrogen in the presence of a hydrogenation-catalyst, the liquidproduct, containing cyclohexanol and cyclohexylamine, from the aniline (or nitrobenzene) converter is separated from ammoniacal water and is then submitted to catalytic dehydrogenation in the presence of steam, this reaction being effected in two or more stages of increasing temperature up to at least 240 DEG  C. and with separation of gaseous constituents and ammon iacal water between each stage, whereby cyclohexylamine is hydrolysed to cyclohexanone.  In a example aniline vapour with the same weight of steam is passed with hydrogen at 200 DEG  C. over a nickel-on-pumice catalyst.  The effluent from the reactor is passed through a condenser into a separator, maintained at 70 DEG  C., in which the gaseous constituents are separated.  The ammoniacal layer is separated from the oily layer of the liquid product.  This oily layer, which comprises cyclohexanol, cyclohexylamine and dicyclohexylamine, is passed with an equal weight of steam over a copper-on-silica catalyst maintained at 240 DEG  C.  The effluent from the second reactor is passed through a condenser to a gas-separator.  The oily layer from the separator is then passed with steam over a copper-on-silica catalyst maintained at 270 DEG  C.  The effluent from this last reactor is passed through a condenser to a gas-separator; and the oily layer from the latter is distilled to separate cyclohexanone.  The chief by-product is cyclohexanol.
